RESUMO
ObjectiveTo study the protective effects of fluvastatin on the renal lesions in diabetic rat. MethodsThe model of diabetic rats was induced by streptozotocin. SD rats were random divided into four groups: Control group, diabetic rats group, low-dose fluvastatin group 2mg/(kg·d) and high-dose fluvastatin group 4 mg/(kg·d). After treatment for 4 weeks, serum cholesterol, serum creatinine and urinary protein were measured respectively. The expression of TGF β1 in the renal cortex was determined by RT-PCR. ResultsFluvastatin inhibited the expression of TGF-β1 Mrna in a dose-dependent manner, and had no influence on urinary protein, serum cholesterol and serum creatinine. ConclusionsFluvastatin inhibits the overexpression of TGF-β1Mrna, which may be related to independent cholesterol decreasing effect.
